I did a walk-around today and found a couple areas of frost heaving. Since this was mentioned here lately, I thought I'd take a couple pictures and post them. Because some members in the southern zones and far northern zones may have never seen this. This is what happens when rain or a heavy wet snow melts, soaks in about 6 to 8 inches, then the temperature drops to overnight lows about 10 degrees F for a couple night and freezes. Then melts and refreezes alternately between freeze/thaw cycles. As the ground freezes deeper to a level of 3 to 4 inches, the already frozen ground at the surface is no longer elastic and cracks. And the cracks get wider with each thaw/freeze cycle. These pictures show many, many freeze/thaw/freeze cycles experienced here in S. E Wisconsin this past winter. In the example shown, the mother bulb is safe below any of this activity, but a 'year old' offset and several of last years offsets along with stem were forced up.
